Through the constitution above, the desired quadratic BPF is realized by having only to the two voltage controlled current sources 13, 15. Thus, the element area is saved through the circuit integration and the cost is much reduced.

Title: Image forming device and counting method
Inventor: ITO TETSURO
IPC: B65H7/02
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To detect appropriate maintenance timing even when various types of recording sheets are mixedly used by adding a value in accordance with recording sheet information detected by a sheet information detecting device to the counted value of a counter by using an adder device. SOLUTION: This image forming device A1 is equipped with a maintenance counter 31 for detecting the mainteance timing. A controller 2 adds a value in accordance with the quality of recording paper where an image is formed to the counted value of the counter 31. In such a case, the value to be added is previously set based on paper powder producing amount per recording paper in accordance with the quality of the recording paper. Therefore, the added value is different in accordance with the quality of the recording paper where the image is formed. The counted value of the counter 31 is nearly proportional to the integrated paper powder amount generated in the image forming device. Therefore, the maintenance is performed at an appropriate time by setting the maintenance time of the individual parts of the image forming device based on the counted value of the counter 31.

Title: Production of trehalose
Inventor: YOSHIDA MASAHIRO
IPC: C12R1/01
Filed: 1995-09-11
Abstract: PURPOSE: To obtain trehalose in high yield by reacting a maltophosphorylase and a trehalose phosphorylase prepared by culturing a specific microorganism belonging to the genus Plesimonas with maltose in the presence of phosphoric acid. CONSTITUTION: A maltophosphorylase and a trehalose phosphorylase which are intracellular or extracellular enzymes obtained by culturing Pleslmonas SH-35 (FERM BP-5144) are reacted with maltose in the presence of phosphoric acid. The pH is readily regulated and reaction proceeds even at a relatively high temperature and substrate concentration. Thereby, the trehalose can be obtained in high yield while preventing the contamination with various germs.

Title: Apparatus for detecting element temperature of oxygen concentration sensor
Inventor: NAKAMURA MICHIO
IPC: G01K7/00
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To make accurately detectable the element temperature by using an impedance value and admittance value as parameters for judging the element temp. of an oxygen concentration sensor. SOLUTION: The sub-microcomputer 18 of a sensor control circuit 16 controls a sensor element 14 so as to hold the applied voltage thereof to be a desired voltage and starts air/fuel ratio feedback when the sensor element 14 is raised in temp. from an in active state to a semi-active state to perform control in an active state. The sub-microcomputer 18 changes over the applied voltage from a reference voltage to a sweep voltage and an impedance value and an admittance value are calculated by respective calculation means. Since the control of the heater 15 at the temp. (element temp.) of the sensor element 14 is possible in the active state, admittance is calculated and the supply of a current to the heater 15 is subjected to feedback control so as to coincide with the objective admittance of the sensor element 14.  However, the accurate detection of the element temp. is performed only in a high temp. region from admittance and the element temp. in the unactive state is accurately detected from impedance.

Title: Ink jet recording method
Inventor: TANAKA KEIKO
IPC: B41M5/52
Filed: 1986-09-30
Abstract: PURPOSE:To enable high-quality printing irrespective of the quality of a paper, by heating an ink adhered to a recording medium to a specified temperature, and recording on a recording paper having a specified sizing degree at a specified contact angle. CONSTITUTION:A heating element 12 is provided on the back side of a stationary platen 1 not facing a recording head 5, and a recording paper 3 is brought into sliding contact with the platen 1 heated by the heating element 12, whereby the paper is preheated and heated to 80-140 deg.C through contact heat transfer around the timing of ink jet recording. If the temperature exceeds 140 deg.C, the paper smokes or is changed in color, whereas when the temperature is lower than 80 deg.C, evaporation of a recording liquid takes place slowly, so that a long time is required for the liquid to be fixed to the paper, and printing quality is poor. Where the preheating and heating temperatures are 80-140 deg.C, recording with high image quality can be achieved when the contact angle (indicating the wettability) of an ink used is 20 deg. at 80 deg.C for an intermediate-quality or woodfree paper having a sizing degree of at least 5sec. When a medium-quality or woodfree paper having a sizing degree of not more than 5sec is used, penetration of the ink into the paper occurs earlier than the evaporation of the ink after the ink is adhered to the paper, so that recording with high image quality can not be achieved. Therefore, papers having a sizing degree of at least 5sec are useful.

Title: Semiconductor wafer and its manufacture
Inventor: KURITA HIDEKI
IPC: H01L21/304
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To make easy and accurate the angularly aligning optical work of a device creating process, by applying no chamfering to the orientation-flat portion of a wafer to machine only its side surface, and by making its side surface orthogonal to the top and rear surfaces of the wafer. SOLUTION: In the chamfering process of a semiconductor-wafer manufacturing process, machining only the side surface of the orientation-flat portion of a wafer, no chamfering is applied to the orientation-flat portion to make its side surface orthogonal to the top and rear surfaces of the wafer. Also, applying chamferings to the outer peripheral side surface of the wafer wherefrom the one of the orientation-flat portion is excluded, its side surface and its top and rear surfaces are connected continuously by curves. In this case, the machining means such one as a grinding other than a cleavage. Also, in the machining, a regrinding, chemical etching, or the like after performing the machining is included too.  As result, facilitating the focussing of a microscopy on the ridge formed out of the side and top surfaces of the orientation-flat portion, its angularly aligning accuracy is improved.
